(ICI. 292-43) 4 Claims.

The object of my invention is to provide a novel roller latch to operatequietly and effectively and will eliminate the scraping of the latchwhich occurs with the bevel latches now in general use. I attain theseand other objects of my invention by the mechanism illustrated in theaccompanying drawings, in which:

Figure 1 is a top plan view of a latch, a portion of the latch socketbeing shown in section;

Fig. 2 is an end View of the latch;

Fig. 3 is a plan view of the socket member;

Fig. 4 is a side elevation of the latch;

Fig. 5 is a side elevation of a modified form of the latch with themodified latch socket shown in vertical section;

Fig. 6 is a perspective view of a modified form of the inventionillustrating a roller latch applied to a door;

. Fig. 7 is a top plan View of the roller latch with the latch socketshown in section;

Fig. 8 is a side elevation of the roller latch shown in Fig. 7;

Fig. 9 is a face view of the socket member of the roller latch; and

Fig. 10 is a front elevation of the latch -member and adjacent parts ofthe door.

Like numerals indicate like parts in each of the several views.

Referring to the accompanying drawings, I provide a rubber ball l,rotatably mounted on an axle 2, which is mounted in a bracket 3, whichis integral with a base 4, that is fastened to the door 6, by screws 5.I provide a latch frame or base 1, having an integral socket adapted toreceive the rubber ball I. The sides 9 of the socket element 8, arebeveled as shown in Fig. 1 and the base 'I is fastened to the door frameby screws IB.

Referring to Fig. 5, there is illustrated a modified latch socket I2having an integral base II, which is fastened to the door frame. Thesocket member I2 has a curved or beveled lip I3 for the rubber ball toroll over. Base II is fastened to the door frame by screws I4.

In use the resilient ball latch rides over the f Referring to themodified form of the invention shown in Figs. 6-10, I provide a rollerlatch I5 mounted on the axle I6, which in turn is I'I extending from thebracket base I8. Bracket base I8 has a stem IS,

on which is mounted a spring 20, tending to press the roller latchoutwardly. Bracket base I8 is slidably mounted in a guide or socket 22provided in a housing 2I mounted in the edge of the door. Roller latchI5 normally seats in the socket 24 of the door latch member 23.

In operation the roller I5, carried by bracket Il, and base I8, isresiliently pressed outwardly by the spring 20 and will ride into a seatin the roller socket '24 to securely hold the door in latched position.

What I claim is:

l. A roller latch comprising a rigidly mounted bracket having laterallyspaced outwardly extending arms, a roller element formed of elasticmaterial and rotatably mounted between said arms, said roller beingtapered outwardly to provide a relatively narrow resilientlycompressible peripheral portion, and a latch socket having a recessshaped complementary to the peripheral portion of said roller, and abeveled portion extending from the edge of said recess and adapted toprogressively compress said peripheral portion as the roller approachessaid socket.

2. A roller latch comprising a rigid bracket having laterally spacedoutwardly extending arms, a spherical roller formed of elastic rubberymaterial and rotatably mounted on a rigid axle extending diametricallytherethrough, said axle being mounted between the ends of said arms, alatch socket operatively mounted for engaging said roller latch andprovided with a complementary segmental spherical shaped recess forengaging said spherical roller and a beveled portion extending from theedge of said recess for progressively compressing the peripheral portionof said roller as the roller approaches said socket.

3. A roller latch comprising a rigidly mounted bracket having laterallyspaced outwardly extending arms, a roller element formed of elasticmaterial and rotatably mounted between said arms, said roller beingtapered outwardly to provide a relatively narrow resilientlycompressible peripheral portion and a latch socket comprising a marginalflange for securing the same to a support, a raised central portionjoined to said ange by inclined walls and a recess in said centralportion complementary to the peripheral portion of said roller, one ofsaid inclined walls serving to engage and progressively compress saidperipheral portion as said roller approaches said socket.

4. A roller latch comprising a rigidly mounted bracket having laterallyspaced outwardly exripheral portion of said roller., 'the edge of said10 .1,463,385

portion being curved to provide a lip serving to engage andprogressively compress said peripheral portion as said roller approachessaid socket- JOHN WARREN AURANDT.
